Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 169)

Module Parameters B-7
38 [DSI I/O Act 3]
Displays the CH3 drives that are active in
Multi-Drive mode.
Default: xxx0 0000
Bit Values: 0 = Drive Active
1 = Drive Inactive
Type: Read Only

43 [Drv 0 Addr 3]
[Drv 1 Addr 3]
[Drv 2 Addr 3]
[Drv 3 Addr 3]
[Drv 4 Addr 3]
Sets the corresponding node addresses of the
daisy-chained CH3 drives when the module is in
Multi-Drive mode.
Important: The setting for each of these
parameters must match the drive Parameter 104 -
[Comm Node Addr] value for each respective
drive. Each drive node address must be unique
(no duplicate node addresses).

Default: 100
Minimum: 0
Maximum: 247
Type: Read/Write
Reset Required: Yes
44 [RTU Baud Rate 3]
Sets the baud rate used by the CH3 drives when
the module is in Multi-Drive mode and Parameter
37 - [DSI I/O Cfg 3] is set to “5” (RTU Master).
Default: 0 = 38.4K bps
Values: 0 = 38.4K bps
1 = 19200 bps
2 = 9600 bps
3 = 4800 bps
4 = 2400 bps
5 = 1200 bps
6 = 600 bps
7 = 300 bps
Type: Read/Write
Reset Required: Yes
45 [RTU Format 3]
Selects the RTU format used by the CH3 drives
when the module is in Multi-Drive mode and
Parameter 37 - [DSI I/O Cfg 3] is set to “5” (RTU
Master). The RTU format consists of three
components: data bits (8 data bits only), parity
(None, Even or Odd), and stop bits (1 or 2).
Default: 0 = 8-N-1
Value: 0 = 8-N-1
1 = 8-E-1
2 = 8-O-1
3 = 8-N-2
4 = 8-E-2
5 = 8-O-2
Type: Read/Write
Reset Required: Yes
46 [RTU Rx Delay 3]
Sets the CH3 inter-character delay used to detect
the end of a receive packet when the module is in
Multi-Drive mode and Parameter 37 - [DSI I/O
Cfg 3] is set to “5” (RTU Master). If this value is
set to 0 (zero), the ModBus default delay of 1.5
character times is used.
Default: 0 milliseconds
Minimum: 0 milliseconds
Maximum: 500 milliseconds
Type: Read/Write
Reset Required: Yes
